PUMP.

SPECIFICATION forming part of Letters Patent No. 750,560, dated January26, 1904.

A li ation fil d Novemberll, 1903. Serial No.180,788. (No model.)

To all whom it may concern:

Be it known that I, OHARLEs J OSEPH ALLEN, a citizen of the UnitedStates, residing at Sabina, in the county of Clinton and State of Ohio,have invented new and useful Improvements in Pumps, of which thefollowing is a specification.

This invention has relation to pumps, and has for its object theprovision of a pump of novel form, construction, material, andcombination of parts that will be especially adapted for use in pumpingliquid from a barrel or cistern and which will be non-corrodible in allthose parts which come into contact with the liquid and simple, strong,durable, and comparatively inexpensive and which may be readily adaptedby a slight change in the length of the barrel of the pump to operate incisterns of greateror less depth.

In carrying my invention into eifect I construct the barrel and thestock of the pump of wood and the valves and such other of theappurtenant parts of the pump as will come into contact with the liquidof suitable non-corrodible materials, the whole being so constructedthat it may be readily set up or taken apart for cleaning or repairs.

In the accompanying drawings, illustrating my invention, Figure 1 is avertical sectional View of the complete pump; Fig. 2, a transversesectional view of the stock of the same; Figs. 3, 4E, and 5, detailviews of parts of the valves; Fig. 6, a side elevation of the pumppistonand apart of the rod, and Fig. 7 a side elevation showing my improvedpump in position over a barrel.

In the several figures of the drawings corresponding letters ofreference indicate like parts.

A designates the body of the pump, which is composed of a singlecylindrical section of wood, having an enlarged head or cap B, throughwhich passes the pump-rod C, provided, as shown, with a handle D. Thesection A is formed with a central cylindrical chamber E, into which thepump-rod G extends, said pump-rod carrying a plunger F, secured in placeupon the end of the rod by a cotter-pin G and having upon the top aflexi- "in position in a barrel.

ble disk H. The plunger F is made of suitable non-corrodible material,preferably of a 'vitreous material, such as porcelain, and, as shown inFig. 4:, is of cylindrical .form and provided with semicylindricalgrooves F F in its periphery to be pumped.

The body A of the pump is somewhat diminished in diameter at its lowerend, and a stock H, which is of the same material as the body of thepump that is, of wood-is formed at its upper end I to [it within thecylindrical bore of the pump-body A, a shoulder 11 upon the stock 11serving to sustain the body upon the stock and limiting the distancewhich the stock will extend into the body A. Upon the top of the stock His arranged a flexible valve K, which is composed of leather or othersuitable non-corrodible material and is held in position by a pin L, ofwood, rubber, or other non-corrodible material. A disk H, of suitableflexible material, such as rubber or leather, is arranged upon the topof the plunger or piston F and fits snugly within the bore of the bodyA. l

The stock H of the pump is, as shown in cross-section in Fig. 2,composed of two halffor the passage of the liquid sections, one of whichis formed with tongues h, fitting the corresponding grooves ii in theother section, the two sections being held together by wooden pins 71.,that pass transversely through the stock and centrally of the tongue72,.

The pump constructed as above described is specially adapted for use inpumping from a barrel or from a cistern, and I have shown in Fig. 7 ofthe drawings my improved pump The stock of the pump, being readilyremovable from the body A, may, if desired, be used with the pump inconnection With a barrel or other receptacle or be removed and replacedby' a barrel of less length than is required when pumping from a cisternor other deep receptacle.

The entire body of the pump, and the stock as well, being composedwholly of wood is non-corrodible, and the pump piston or plunger, thevalves, and the device securing the valves in place being all ofnon-corrodible material the pump Will consequently be strictlynon-corrodible in all the parts which come into contact with the liquidbeing pumped.

Having described my invention, What I claim, and desire to secure byLetters Patent, 1s

The combination with the wooden pumpbody A having a cylindrical bore Eand an integral head B of the pump-rod H, the cylindrical vitreouspiston or plunger F formed with vertical grooves f the stock H and thevalves H and K secured respectively to the top of said stock and to theplunger 0r piston, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
